CAN.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed May 23, 1917. Serial No. 170,342.

To all whom t may concern:

Be it known that I, RALPH W. CRARY, a citizen of the United States, residing at Vaukesha, in the county of Waukesha and State of Wisconsin, have invented a new and useful Can, of which the following is a specification.

The object of my invention is to produce a simple and ellicient sealing ring for that type of cans comprising mating circumferential flanges of can body and cover.

The accompanying drawings illustrate my invention. Figure 1- is a perspective frag` strip comprises a ring having flanges 15 and 16 which may be either initially formed parallel with each other, as shown in Fig. 1, or may be formed at right angles to each other, as shown in Fig. 2.. The mating ends of the ring are formed -with quite short overlapping tongues 15 and 16, so that they overlap above and below the flanges 10V and 13 for a short distance. By this arrangement,

the aibutting ends of the ring are stepped relative to each other, and the projecting tongues being comparatively short, the overlapped stepped portions have suflicient rigidity to firmly hold the overlaid portions of the can flange and cap flange, respectively. The ring. is either slipped endwise upon the flanges, if of the initial form shown in Fig. 2, or Wrapped around the edges of the flanges if of the initial form shown in Fig. 1. If of the form shown in Fig. 2, flange 16 is then rolled beneath flange 11 of the can, and in either case the two flanges 15 and 16 are rolled tightly upon the flanges 10 and 13, the inner edge of flange l5 being down* turned over the inner edge of the portion 14, thus firmly clamping the cover upon the can.

I claim as my invention:

The combination With la can and cover having mating circumferential flanges, of a sealing ring applied to said circumferential flanges, said sealing ring comprising a strip of material having substantially parallel flanges embracing the circumferential flanges of the can and cover and having abutting ends in the form of short lingers which are stepped and disposed in abutting relation, one contacting the flange-of the cap and the other contacting the flange of the can.

In witness whereof, I have hereunto set my hand at Vaukesha, Wisconsin, this seventeenth day of May, A. D. one thousand nine hundred and seventeen.

RALPH W. CRARY.
